Ultra-high Bandwidth 6-Phase PWM Controller With 8 Bit VID Code Capable Of Precision RDS(ON) Or DCR Differential Current Sensing

The ISL6307A controls Microprocessor core voltage regulation by driving up to 6 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved Timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area.
Microprocessor loads CAN generate load transients with extremely fast edge rates. The ISL6307A features a high bandwidth control loop and ripple frequencies up to 12MHz to provide optimal response to the transients.
The ISL6307A senses current by utilizing patented techniques to measure the voltage across the on resistance, RDS(ON), of the lower MOSFETs or DCR, of the output inductor during the lower MOSFET conduction intervals. Current sensing provides the needed signals for precision droop, channel-current balancing, and overcurrent protection. A programmable internal temperature compensation function is implemented to effectively compensate for the temperature coefficient of the Current Sense element.
A unity gain, Differential Amplifier is provided for remote voltage sensing. Any potential difference between remote and local grounds CAN be completely eliminated using the remote-sense Amplifier Eliminating ground differences improves regulation and protection accuracy. The thresholdsensitive enable input is available to accurately coordinate the start up of the ISL6307A with any other voltage rail. Dynamic-VID technology allows seamless on-the-fly VID changes. The offset pin allows accurate voltage offset settings that are independent of VID setting.
